PM2.5 coagulant and preparation method thereof

Abstract

The invention discloses a PM2.5 coagulant and a preparation method thereof. The PM2.5 coagulant comprises, by weight, 0.1-0.5% of organic adhesive, 1-20% of polyol, 0.1-2% of natural plant gel, 1-10%of antistatic agent, 0.5-50% of plant active extract and 17.5-97.3% of deionized water. The PM2.5 coagulant has the advantages that the PM2.5 coagulant can be diluted 50-1000 times with water according to conditions and then sprayed into the air, PM2.5 content in the air can be reduced by forming sealing objects through static adsorption, agglomeration, settling and adhering, and the PM2.5 coagulation rate of the PM2.5 coagulant can reach 90% or above.

Description

technical field

[0001] The invention relates to the field of ecological environment protection, in particular to a coagulant for reducing the value of PM 2.5 in the air and its preparation method and application. Background technique

[0002] PM2.5 refers to particulate matter in the atmosphere with an aerodynamic equivalent diameter less than or equal to 2.5 microns, also known as particulate matter that can enter the lungs. Although PM2.5 is only a small component of the earth's atmospheric composition, it has an important impact on air quality and visibility. Compared with coarser atmospheric particulate matter, fine particulate matter has a smaller particle size, is rich in a large amount of toxic and harmful substances, has a long residence time in the atmosphere, and has a long transportation distance, so it has a greater impact on human health and atmospheric environment quality. Studies have shown that the smaller the particles, the greater the harm to human health....
